BICYCLE-LANTERN.

SPECIFICATION forming part of Letters Patent No. 559,948, dated May 12, 1896.

Application filed August 7, 1895.

To all whom it may concern:

Be it known that I, FRANK RHIND, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Bicycle-Lanterns, (Case A;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to bicycle-lanterns, and has for its object to produce a body for bieycle-lanterns which shall be made from two pieces of metal which are secured together without solder, thus doing away with one of the most objectionable features of the present mode of constructing the bodies, it being practically impossible where the parts of the body are soldered together to prevent the solder from showing more or less upon the outer side of the body.

My invention furthermore has for its object to provide a construction of body which will retain the back reflector in place without the use of additional pieces. My invention furthermore has for its object to provide a construction of body in which outside ways for the sliding side light shall be wholly dispensed with; and myinvention furthermore has for its object to provide a construction of body in which the bracket-supports shall be made integral with one part of the body, my novel body as a whole being neater in general appearance than where solder is used in securing the parts together, being stronger and more rigid, and being much less expensive to make than the lantern-bodies heretofore placed upon the market.

lVith these ends in view I have devised the novel construction of which the following description, in connection with the accompanying drawings, is a specification, letters and numbers being used to designate the several parts.

Figure l is a side elevation illustrating my novel lantern-body in connection with the other parts of a search-light lantern, the body being in full lines and the other portions of the lantern in dotted lines; Fig. 2, a plan view of the body assembled, the position of Serial No. 558,525. (No model.)

the back reflector being indicated in dotted lines; Fig. 3, a side elevation of the inner part of the body detached; Fig. 4, a section on the line 50min Fig. 2; Fig. 5, aview of the blank from which the part of the body illustrated in Fig. 3 is formed; Fig. 6, an elevation of the outer part of the body and Fig. 7 is an elevation, the point of view being at right angles to the point of view in Fig. 6.

A denotes the outer part of my novel lantern-body, and B the inner part. Part A is cylindrical in form and seamless, this part being in practice drawn from a disk of metal.

In the front of part A is an opening 1 to receive the front reflector 2, which is shown only in dotted lines in Fig. 2. At right angles to opening 1 is an opening 3, in which is fixed the stationary side light at. On the opposite side from opening 3 is a rectangular opening 5 to receive the sliding side light 6, as will be more fully explained, and at right angles to opening 3 and opposite to opening 1 is a rectangular opening 7, which receives a portion of part B when assembled, as will be more fully explained. Part B is blanked out from sheet metal to substantially the form shown in Fig. 5, and is then formed to the shape indicated in Figs. 1, 2, and 3. S denotes an opening in part B, which registers with opening 5 in part A and leads into the combustion-chamber. This openingis closed by the sliding side light, as will be more fully explained. 9 denotes the back reflector, which is indicated by dotted lines in Fig. 2. One end of the reflector is held in position by a lug or lugs 10, formed by striking in the metal of part B, and the other end of the reflector is held by a flange 11, formed by turning inward the other end of part B, as is clearly 0 shown in Fig. 2. The line at which the lug or lugs are struck in and the line at which the flange is bent are indicated by dotted lines 10" and 11 in Fig. 5.

It will be noticed that in my present lantern lug 10 and flange 11 lie at an acute angle to the vertical plane, so that the upper end of the reflector will incline forward toward the front of the lantern. So far as my present invention is concerned, however, it is imma- I00 terial whether the reflector is placed vertically or is inclined in either direction relatively to the vertical plane. At the back of the lantern is an air-duct 12, into which outside air is admitted through openings 13, and from whence it passes into the body of the lantern to facilitate combustion. It will of course be obvious that the exact shape of this air-duct is not of the essence of my invention. It is furthermore obvious that any required shape within reasonable limits may be imparted to the d uct by blanking out part B to the necessary shape to produce the required shape after the blank has been formed. The gist of this portion of my invention lies in forming an air-duct from the metal of part B which shall extend through opening 7 in part A, and also in forming from the metal of part B the brackets to which the spring-carrier is pivoted. 14 denotes the brackets and 15 the spring-carrier which is pivoted thereto, said spring-carrier appearing only in dotted lines in Fig. 1. The duct is formed by bending the metal of part B inward at the horizontal lines indicated by 16 in Fig. 5, bending again at the horizontal lines indicated by 17, leaving the flanges of metal indicated by 18 and 19 in the vertical plane, the central portion of part B, which I have indicated by a, formin g the back of the air-duct, and the portions indicated by b and 0, respectively, forming the top and bottom of the air-duct. The metal of part B is also bent inward at the vertical lines indicated by 20 and outward again at the vertical line indicated by 21, the portion of part Bindicated by (Z forming the sides of the air-duct. lVays 27 for the sliding side light are formed between parts A and B by offsetting the metal at the horizontal lines indicated by 22 in Fig. 5, so that while the top and bottom of this portion of part B lie closely in contact with part A the central portion is oifset inward and forms in connection with the part A the ways or recess, which I have indicated by 27, in which the side light 6 slides, opening 5 inpartA being large enough to permit said sidelight to be moved far enough toward the back to uncover opening 8 in part B. The frame of side light 6, which I have indicated by 28, is made of suitable size to slide in the ways and of greater size than opening 5, so that said side light will be held securely in position between said parts A and B when assembled. The ends of part B and the flanges 18 and 19 are formed to the proper curvature of the body of the lantern.

In assembling, part B is placed within part A, the air-duct and brackets being passed through opening 7 at the back of part A. In practice, flange 18 of part B lies within part A and flange 19 lies outside of part A. These, however, are mere details of construction which are not of the essence of my invention. After assembling, parts A and B are rigidly secured together by rivets 23, no solder whatever being used in the entire structure of the body of the lantern.

2i denotes a plate which closes the inner side of the air-duct, said plate, however, be-

ing provided with openings which permit air to pass freely through the duct into the body of the lantern, but as the openings do not register with the openings in the other walls of the duct it is impossible for air to enter the body of the lantern in a current strong enough to effect the flame, the air currents in the duct being, as a matter of fact, broken up and distributed over the entire area of plate 2-l. This plate may beheld in position in any ordinary or preferred manner. I have shown lugs 26 formed on part B by striking in the metal at the vertical lines indicated by 21 in Fig. 5.

7 Having thus claim 1. A bicycle-lantern body consisting of a part A having an opening 7, and a part B adapted to lie within part A and having an air-duet provided with openings for the admission of air formed from the metal of said part B and extending throughopening 7.

ment of a spring-carrier formed from the metal of said part B and extending through opening 7.

5. In a bicycle-lantern body the combination with a part A having an opening 7, of a part B adapted to lie within part A and having an air-duct provided with openings for the admission of air and brackets for the attachment of a spring-carrier formed from the metal of part B and extending through opening 7, a lug 10 and a flange 11 formed on said part B and lying within part A and a back reflector which is held in position by said lug and said flange.

6. In a bicycle-lantern body the combination with a part A having an opening 7, of a part B adapted to lie within partA and hav ing an air-duct provided with openings for the admission of air formed from the metal of said part B and extending through opening '7 lugs 26 formed on part B and lying within part A and a plate 2i having openings 25 for the passage of air from the duct into the body, said plate being held in position by said lugs.

'7. A bicycle-lantern body consisting of a part A having an opening 5 to provide for a sliding side light and an opening 7, a part B adapted to lie within part A and having an air-duct provided with openings for the admission of air and brackets for the attachment of a spring-carrier formed from the metal of said part B and extending through opening 7, said part B being provided with an opening 8 and being offset to form ways 27 between said 15 parts A and B to receive a sliding side light and rivets 23 by which the parts are held together without solder.

In testimony whereof I affix my signature in presence of two witnesses.
